Product Details

Built around a 21mm x 15mm objective lens with multi-layer coating, the Thrive HD is designed to deliver a clear sight picture in varying light conditions. The multi reticle functionality is one of the defining features of this optic, giving shooters the option to select between a precise 3 MOA centre dot for accurate longer-range aiming, or a wider 42 MOA circle for rapid close-range acquisition and faster re-engagement following recoil. This adaptability makes the sight suitable across a range of applications, from pistol-mounted use to rifle and shotgun setups.

Shake awake technology, combined with an auto sleep and auto-on motion sensor, keeps the sight ready without unnecessary battery drain, contributing to a rated battery life of up to 50,000 hours on a standard CR2032 cell. The housing is shockproof, waterproof and fog-proof, with an operational temperature range of -20°C to +70°C, making the Thrive HD suited to demanding outdoor use throughout the UK shooting season.

At approximately 19 grams with the battery fitted, the Thrive HD is one of the lighter micro reflex sights available, helping to maintain balance on lighter platforms without compromising on the durability expected from a ZeroTech optic. It fits all Shield RMSc footprint mounts and bases, making it a straightforward option for anyone already using RMSc-pattern optics or looking to standardise their mounting setup.

Each Thrive HD comes complete with a rubber protective cover, a microfibre lens cleaning cloth, hex keys for sight attachment and three sets of mounting screws, giving you everything needed to fit and protect the sight from the outset.

Backed by the RMSc footprint compatibility and ZeroTech’s Triple A Lifetime Warranty, it’s an optic built to be used regularly without the need to think twice about durability or reliability.
